A synthesis of β-ketosulfones via sulfination of aryl methyl ketones and aryl acetylenes with sodium sulfinates under mild electrochemical conditions, in moderate to good chemical yields, is described. In particular, an electrochemical sulfination reaction of alkynes with sulfinate salts has never been explored. An environmentally friendly characteristic of this reaction is that it uses electricity as a valuable energy source for electrochemical synthesis of β-ketosulfones. This strategy is more convenient and practical compared to previous approaches.

从可转换的起始原料电化学合成β-酮砜。

描述了在温和的电化学条件下以中等至良好的化学产率通过亚磺酸钠与芳基甲基酮和芳基乙炔的硫化反应合成β-酮砜的方法。特别地,从未探索炔烃与亚磺酸盐的电化学硫化反应。该反应的环境友好特性是它使用电作为电化学合成β-酮砜的宝贵能源。与以前的方法相比,此策略更加方便实用。
